No flame intended, but it sounds a bit like you might be in over your head. Better let a qualified repair shop finish up the job for you. Not only do you need to replace the refrigerant oil and vacuum the system, but you also need to recheck for leaks and and proper system performance as well as correct refrigerant charge.

The system absolutely has to be evacuated before charging a depleted system. That performs several functions including ensuring that the system will retain the refrigerant when charged.
